Up-to-date since commit: d343135abe - Allow spellcasting if hands are stuck to a quarterstaff

This repo is the home of my experimental changes to NitroHack. So far, I've ported most of UnNetHack up to and including the Advent Calendar branch, and have switched over to merging selected parts of NetHack4. More recent parts of UnNetHack will be ported once they've had some time to settle, e.g. Sheol, pre-fabricated vault rooms.

If you want to follow NitroHack actual, see DanielT's repo instead. See also NetHack4, which merges NitroHack and AceHack and is under continuing development.

Merged changes from GruntHack

GruntHack is a variant of NetHack that was "aiming the extend and enhance existing behaviour", at least until it was discontinued in late 2012. It's similar to Slash'EM in spirit, but rather than adding a ton of stuff, it extends what's already in NetHack. Objects can have magical properties ("short sword of fire", "rotproof chickatrice corpse"), materials ("large bone box", "dragonhide T-shirt"), be invisible and distort under hallucination. Monsters get many of the abilities previously restricted to players (e.g. player spells, water walking, displacement, strength, fumbling) and vice versa. Monsters also have vastly improved AI (pets use ranged attacks, monsters can open containers and make wishes, petrifying spellcasters cast stone-to-flesh on themselves, wandering adventurers can steal the Amulet of Yendor and ascend on the Astral Plane).

I probably won't port much from GruntHack, whose focus is on raising the stakes for both players and monsters. It does have some interesting features that wouldn't be out-of-place in other variants though.

Items

• Magical object properties - e.g. short sword of fire, bow of detonation, cloak of magic resistance and reflection.
  • Objects with identical properties stack even if known properties differ.

Interface

• Dynamic lighting - like darkroom, but dims everything (e.g. objects and traps) outside the field of view.

Merged changes from NetHack4

NetHack4 is a merge of NitroHack and AceHack, and focuses on playing mostly the same as classic NetHack with a modernized interface, except removing "interface screws", e.g. floating eye paralysis, Stormbringer's hostility, amnesia, renaming AC as "Defence", asking before eating a rotten corpse, walking into water or lava, or putting a dangerous item into a bag of holding.

Some of the AceHack-like changes ruin the fun of NetHack a little, so the changes that will be merged will mostly be bug fixes and pure interface improvements. See NetHack4 Omissions for the rationale of leaving out certain changes.

Gameplay

• Light sources show fuel left if they're seen consuming it, e.g. when they flicker or go out.
  • Charging (e.g. scroll or PYEC) identifies charges as well as recharging the object.
  • Light sources are marked as cursed when they fail to light.
• Items stack regardless of BUC knowledge.
  • Don't stack unnamed items with named items.
• Formally identify wands when engraving gives a unique message.

Interface

• Door coloring for trap/lock status: trapped doors appear cyan, locked doors appear red, unlocked doors appear green; controlled with the mapcolors option.
• New hilite_peaceful option: display peaceful monsters in inverse, like pets with hilite_pet.
• Stairs/portals get a red background, object stacks get a blue background.
  • colormap.conf: Colors used by the game can be remapped to terminal colors of the player's choice.
• Show intrinsics, extrinsics and experience to the next level in Ctrl-X character info listing.
  • Allow viewing kills, genocides and conducts from Ctrl-X character info screen.
• Newly displayed statuses: levitation ("Lev"), unarmed ("Unarmed"), trapped ("Trap")
• Give monsters with overlapping appearances a unique color/underline (brighter and underlines = stronger).
• Show messages by screenfuls with --More--.
• Show skill slots required to raise skills that can be advanced in the #enhance menu.
• Swapping weapons with x no longer takes time.
• Don't say, "You climb up/down the ladder."
• Move wand breaking from apply (a) to #invoke (V).
• New a, shortcut for #loot.
  • Require q, to quaff from fountains and sinks.
  • Require , to select floor items when eating, tinning and sacrificing.
• Map under cursor described when targeting locations.
• Use more portable Unicode characters for dungeon features.
• Populate in-game database/encyclopedia with basic item descriptions.

    • Link zlib with game library to fix OS X build failure (Marco Bonetti).

Progress of UnNetHack port

In general, all code that references UnNetHack changesets is credited to Patric Mueller, and anything else is my original work, unless otherwise stated.

See Omitted Changesets for what's been left out, e.g. externalities like livelogging and mail are omitted since they're hard to test and NitroHack's new architecture might have better solutions anyway.
